SWIPE! ⬅️ Extremely rare moment captured at Monument Valley. In 2006, a massive slab of the East Mitten butte collapsed in a dramatic sandstone avalanche. A few visitors happened to be in the right place at the right time and caught this unbelievable moment. 🌄⚡ They described it as a once in a lifetime sight. 📸 Credit: Roylene Garrett #welcometoarizona #monumentvalley #arizona #naturelovers #travelarizona #desertviews #arizonahistory #explorearizona #visitusa #geologywonders
